How can zinc be separated from lead in the condenser?
In the blast furnace a mixed lead/zinc sinter is added and the lead bullion is tapped conventionally from the bottom of the furnace while metallic zinc vapour is distilled off and captured/condensed by a spray of molten lead droplets. A solution of zinc and lead leaving the condenser, when cooled this cool zinc can be floated off, while the lead is recirculated to the collector. Zinc being less dense can be continuously removed from the top layers.
Does iron ore slag sink to the bottom of the blast furnace?
Slag is the waste which is skimmed off the top of the molten iron that comes out of the blast furnace. It is a mixture of calcium and magnesium compounds, plus other impurities such as iron oxide, but is mainly calcium silicate. The formula for calcium silicate is CaSiO3.
What type of rock form is galena in?
First: Roast the Galena in a blast furnace for 30 minutes. Second: Add Carbon to the blast furnace to remove impurities. Third: Tag off your lead from the bottom of the blast furnace.
Why wont your electric furnace shut off?
Your thermostat might be shorted out. Remove one of the wires off of the stat to see if the furnace will shut down that way.
Why is a blast furnace called a blast furnace and not a furnace or fire furnace?
The basic concept of a blast furnace hasn't changed in more than 100 yrs. Modern furnaces are of course more complex due to newer technologies. First of all the furnace is basically a steel tank, inside it is lined with brick or gunite. The outside shell is protected from the heat by hundreds of "coolers" which are located around the entire furnace. Coolers are usually made from copper and have water inlets and outlets; water does not enter the inside of the furnace but is circulated in a closed loop system through a network of piping. At the bottom of the furnace are openings called tuyeres (ta-weers) through which hot air is blown into the furnace. The tuyeres are connected to a large brick-lined pipe called a bustle pipe. The bustle pipe is connected to a series of very large stoves. Outside air is fed into the stoves where it is heated. The heated air is then blown into the bustle pipe, through the tuyeres and into the furnace. The tuyeres can also be piped to allow the use of oxygen, pulverized coal, and natural gas to enhance the heat. Raw material is loaded into the top of the furnace by conveyor or a skip car which runs on a track pulled by cables. The raw materials are iron ore, limestone, coke and alloys chosen by the steelmaker. At the bottom of the furnace is an opening called the tap hole. The tap hole is plugged by a machine called a mud gun, the mud gun is loaded by hand with "mud" which is a high grade refractory that does not melt under the intense heat. After the materials reach the desired temp (usually about 3500 deg F) another machine called a tap drill drills out the mud to let the molten metal out of the furnace; this is known as "casting". Molten metal and slag are separated by a series of channels, slag (girl) will flow to a pit or slag car to be carried away. The slag is cooled to be used in a variety products such as an additive in concrete. The metal is channeled to bottle cars to be transported to different areas of the mill for processing. This is a very basic overview of a blast furnace, they are highly complex and very dangerous!
How is iron removed from a blast furnace?
Iron is removed from a balst furnace, it melts as it seeps down to the higher temperatures at the bottom of the furnace from where it is tapped off. Hope that helps.
Extraction of lead from galena by heating process?
First: Roast the Galena in a blast furnace for 30 minuets. Second: Add Carbon to the blast furnace to remove impurities. Third: Tag off your lead from the bottom of the blast furnace.

Describe the smelting of iron ore?
You put the ore in the furnace.. Its a bar.. Woooo you produce carbon dioxide and molten iron pour off molten iron mix with limestone and coal and last place with blast furnace
How is iron ore converted into iron?
you can smelt it. You put it in a blast furnace with carbon. This will be able to separate the iron from the iron ore The carbon is in the form of coke, providing both fuel for the huge amount of heat at the high temperature needed, and the carbon necessary to separate chemically the iron from the iron-oxide which is the ore itself. Limestone is added as a flux to help remove silica and other impurities as molten "slag" that floats on the molten iron, and is tapped off separately. The "blast" part refers to the powerful blasts of air pre-heated by the furnace's flue gases, and blown into the fire to raise it to white heat.
When did Blast Off happen?
Blast Off happened in 1989.
How is iron refined?
Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie
How do you identify an electric furnace from a gas furnace?
an electric furnace runs off of 208/230 Volts while a typical gas furnace runs off of 120 also a gas furnace will have a valve for the gas relay where the gas enters the furnace.
What is a sentence using the word blast?
We had a blast! The rocket is about to blast off.
Will carbon escape with the furnace off?
Carbon will not escape with the furnace off and it will only choke you because you will be breathing it carbon not oxygen. So my advice is dont turn the furnace off
What to astronauts use to blast off?
What should be used to apply Blast-Off
